integral of (2x^4-5x^2+1)

\int (2 x^{4} - 5 x^{2} + 1) d x

\frac{2 x ^{5}}{5} - \frac{5 x ^{3}}{3} + x + C

Solution steps

\int 2 x^{4} - 5 x^{2} + 1 d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int 2 x^{4} d x - \int 5 x^{2} d x + \int 1 d x

\int 2 x^{4} d x = \frac{2 x ^{5}}{5}

\int 5 x^{2} d x = \frac{5 x ^{3}}{3}

\int 1 d x = x

= \frac{2 x ^{5}}{5} - \frac{5 x ^{3}}{3} + x

Add a constant to the solution

= \frac{2 x ^{5}}{5} - \frac{5 x ^{3}}{3} + x + C

\int \frac{1}{5 + 2 x - 2 x ^{2}} d x

\int \frac{5 x ^{2} + 2 x + 6}{x ^{3} + 2 x ^{2} + x} d x

\int \frac{cos ( x ) ln ( cos ( x ) )}{csc ( x )} d x

\int \frac{1}{- x ^{2} - 6 x + 16} d x

\int 2 x (x^{2} + 10)^{30} d x
